The specific embodiment is as follows:

referring to fig. 1 to 5, the hose extruder includes a pair of extrusion rollers 1, a pair of clamping plates 2, a driving arm 3, a ratchet 4, a torsion spring 5, and a compression spring 6.

The two ends of the extrusion roller 1 are provided with a shaft section 11, and friction lines 12, such as gear lines in the illustration, are designed on the surface of the extrusion roller to increase the clamping force on the smooth hose; a ratchet wheel 4 is sleeved on the shaft section 11 at one end, and a driving arm 3 and a torsion spring 5 are movably sleeved on the shaft section; that is, the driving arm 3 has a shaft hole 31 at one end and a round pin 32 at the other end; a circular concave part 311 is formed on the inner side of the position of the shaft hole 31, the depth of the circular concave part 311 is equal to the thickness of the ratchet wheel 4, and the ratchet wheel 4 is not arranged in the circular concave part 311 when assembled; a convex circular ring 312 is formed on the outer side of the shaft hole 31, and the torsion spring 5 is sleeved on the convex circular ring 312 during assembly; the round pin 32 provides both the abutting requirement of the torsion spring 5 spring arm and the smooth surface against the clamping plate 2. The drive arm is provided with a reed pawl 33, the end part of the reed pawl 33 is abutted against the ratchet wheel 4, the drive arm 3 swings to stir the ratchet wheel 4 by means of the reed pawl 33, and the extrusion roller 1 is driven to rotate by the ratchet wheel 4.

The two extrusion rollers 1 are in rotationally symmetrical fit, and the two extrusion rollers 1 are correspondingly positioned in the open shaft seat 21 of the clamping plate 2 by virtue of shaft sections 11 at the two ends; an axial locating point 5 which is meshed with each other is arranged between the two clamping plates 2, and the clamping plates are restrained into a whole by means of a compression clamping spring 6 which is symmetrically arranged at two ends, as shown in figure 2. More specifically, the clamping plate 2 has a semicircular head portion 22, a flat tail portion 23 and a binding 24 which can interfere with each other; the shaft positioning point 25 and the open shaft seat 21 are arranged at one end of the semicircular head 22, and the shaft positioning point 25 is arranged on the binding 24; the edge 24 is gradually thinned towards the tail by taking the shaft positioning point 25 as a boundary part, so that a relatively large operation distance is provided for the flat tail parts 23 of the two clamping plates 2, and when the edge 24 of the two flat tail parts are contacted, one end of the semicircular head part 22 is slightly opened so as to be inserted into the flat tail part of the hose. Or, the two flat tail edges 24 of the clamping plate 2 are further provided with micro-convex points or demarcation parts, such as a demarcation line 241 in fig. 1 and 5, so that the two clamping plates have two degrees of expansion, and the two clamping plates rotate around the positioning shaft point 25 to the contact area of the front edge 24 of the demarcation line 241, which is a normal extrusion operation; when the force is continued to be applied again, the force is transferred to the position taking the dividing line 241 as a fulcrum and then to the wrapping edge at the rear side of the dividing line 241 to be contacted, at the moment, the two clamping plates 2 overcome the elastic force of the compression clamping spring 6 again, and under the action of the torsion spring 5, the two extrusion rollers 1 can open a larger gap, so that the hose can be firstly filled into or drawn out of the empty hose, and convenience is provided for replacing the hose.

As shown in fig. 3, one spring arm of the torsion spring 5 is abutted against the driving arm 3, and the other end is abutted against the same side clamping plate 2; the straight tail parts 23 of the two clamping plates 2 are pinched one by one, namely the driving arm 3 drives the ratchet wheel 4 to drive the corresponding extrusion roller 1 to rotate in the opposite direction through the reed pawl 33, namely the hose is rolled inwards from one side of the semicircular head part 22 of the clamping plate, so that paste in the hose is forced to be extruded to the outlet, and the purpose of extrusion is achieved. When the external force applied to the two clamping plates 2 is released, the tail parts of the two clamping plates 2 spring open and reset under the action of the elastic force of the torsion spring 5, and the reed pawl 33 slides over the surface of the ratchet wheel 4 to wait for the next extrusion operation. In practice, when the reed pawl slides over the ratchet wheel, the ratchet wheel can slightly rotate, so that the extrusion force on the tail part of the hose is reduced, the internal pressure of the hose is reduced, and the paste is effectively prevented from continuously flowing outwards, so that waste is caused. The relationship is shown in fig. 4.

The clamping plate 2 is further provided with a baffle plate 26 on the inner side of the wrapping 24, the baffle plate 26 is integrally formed with the open shaft seat 21, an assembly hole 27 is formed on the rear edge of the open shaft seat 21, and a channel for the spring arm of the compression clamp spring 6 to pass through is provided, as shown in fig. 2 and 5. In order to improve the friction force during hand pinching, anti-skid patterns can be formed on the surface of the straight tail part 3. By means of the baffle 26 and the edge 24, an assembly space is formed which constrains the drive arm 3, the ratchet wheel 4, the torsion spring 5 and the compression spring 6.

The shaft positioning point 25 has two structures, namely, one side of the clamping plate is covered with a semicircular convex part 24, the other side of the clamping plate is covered with a semicircular concave part matched with the semicircular convex part, and the two clamping plates 2 can be mutually meshed after rotating to form a shaft fulcrum for positioning point and rocker motion; in the structure, the two clamping plates are of identical structure; in the figure, semicircular concave parts are formed on the wrapping edges on two sides of one clamping plate 2, semicircular convex parts matched with the semicircular concave parts are formed on the wrapping edges on two sides of the other clamping plate, and the two clamping plates can be matched to form shaft positioning, but the two clamping plates are of two different structures, and are required to be formed by two sets of dies, and the two clamping plates are required to be selected during assembly.
