Extruder
An extruder includes a first clamping plate, a second clamping plate, a connecting plate rotatably interconnecting the first and second clamping plate, a latching member, and a positioning protrusion. The latching member is formed on an end of the first clamping plate. The positioning protrusion is formed on an end of the second clamping plate, matching with the latching member to latch the first and second clamping plate.
1. An extruder comprising:
a first clamping plate;
a second clamping plate;
a connecting plate rotatably interconnecting the first clamping plate and the second clamping plate;
a latching member formed on a side of the first clamping plate, located on an end of the first clamping plate away from the connecting plate, protruding obliquely to the first clamping plate at a standing state, defining a latching hole, and a resisting portion protruding from a side of the latching member adjacent to the first clamping plate and positioned adjacent to a side of the latching hole away from the first clamping plate; and
a positioning protrusion formed on an end of the second clamping plate away from the connecting plate,
wherein the connecting plate is capable of bending to move the second clamping plate toward the first clamping plate, and the positioning protrusion is capable of moving into the latching hole to resist along the resisting portion, to latch the first clamping plate and the second clamping plate, and the latching member keeps in the standing state when the positioning protrusion is latched.
2. The extruder of claim 1 , wherein the first clamping plate comprises a base body and an enforcement portion perpendicularly protruding from a side of the base body, and the second clamping plate comprises a base body and an enforcement portion perpendicularly protruding from a side of the base body.
3. The extruder of claim 2 , wherein the enforcement portion of the first clamping plate and the enforcement portion of the second clamping plate define a number of grooves on a same side, respectively.
4. The extruder of claim 1 , wherein the first clamping plate and the second clamping plate cooperatively form a clamp space therebetween after latching the first and second clamping plate, and the vertical height of the clamp space is less than 3 millimeters.
5. The extruder of claim 1 , wherein the connecting plate defines a bent portion on a side thereof.
6. The extruder of claim 5 , wherein the bent portion is a groove.
7. The extruder of claim 1 , wherein the resisting portion comprises:
a guide surface inclined to the first clamping plate;
a resisting surface opposite to the guide surface and parallel to the first clamping plate; and
a connecting surface interconnecting the guide surface and the resisting surface and inclined to the first clamping plate,
wherein the positioning protrusion resists the resisting surface after latching the first and second clamping plate.
8. The extruder of claim 7 , wherein the positioning protrusion defines two arc chamfers on an end thereof.
