[0017] The utility model makes further explanation in combination with the drawings:

[0018] As Figures 1-2 shown, a rubber band pipe clamping and fixing device, the clamping and fixing device includes frame 2, the sliding groove or track is set up in the frame, the sliding frame 3 realizes the removal in the sliding groove or track, specifically adopts the eccentric shaft 4 of the output portion installation motor 1, the eccentric shaft realizes reciprocating motion through movable frame 5 and drive sliding frame 3, the top of sliding frame 3 installs upper cutter 7, the back of frame 2 installs lower cutter 8, clamping assembly 6 is installed in the front of lower cutter 8 through a pair of rotating shafts 9, the rear end of a pair of rotating shafts 9 installs rotating block 10, changes rotating block 10 rotation through toggle piece 11, and then changes rotating shaft rotation direction, the toggle piece 11 is installed on sliding frame 3 through fixed part 12, wherein, clamping assembly 6 is a pair of L-shaped clamping pieces back-to-back and constitutes, the top of L-shaped clamping piece is equipped with semicircular clamping part, when two L-shaped clamping pieces combine, the two semicircular clamping parts of top form circular area, can effectively fix rubber band pipe and clamping cut rubber band, in addition, Figure 2As shown, the two rotating blocks 10 at the rear end of the rotating shaft are horizontally arranged, and the actuating piece 11 is in F shape, when the upper actuating piece of the actuating piece 11 presses the rotating block 10 downward, the pair of rotating shafts 9 are both rotated inward, thereby making the clamping assembly 6 close, when the lower actuating piece of the actuating piece 11 pushes the rotating block 10 upward, the pair of rotating shafts 9 are both rotated outward, thereby making the clamping assembly 6 open, and the actuating piece is installed on the sliding frame through the fixing part 12.

[0019] The specific use principle is as follows:

[0020] Figure 1 As shown, the semicircular clamping part of the clamping assembly 6 needs to be higher than the blade of the lower cutter 8, so that the rubber band pipe passes through the top of the blade of the lower cutter 8 from the back, and the clamping assembly 6 can only be fixed or clamped when it is closed.

[0021] When the motor works, the eccentric shaft is driven to rotate, when the eccentric shaft is at the highest position, the sliding frame 3 and the upper cutter 7 are also at the highest position, and the actuating piece 11 is also at the highest position, at this time, the lower actuating piece of the actuating piece 11 pushes the rotating block 10 upward, the two rotating blocks 10 drive the rotating shafts to rotate outward, thereby making the L-shaped clamping part of the clamping assembly 6 open, and the rubber band pipe passes through the front from the back of the lower cutter 8, the eccentric shaft continues to rotate, the sliding frame 3 and the upper cutter 7 gradually move downward to cut the rubber band, and the actuating piece 11 also continues to move downward, the upper actuating piece of the actuating piece 11 begins to gradually press the rotating block 10, the rotating block 10 drives the rotating shafts to rotate inward, so that the L-shaped clamping part of the clamping assembly 6 gradually closes, when the sliding frame 3 and the upper cutter 7 are also at the lowest position, the actuating piece 11 is also at the lowest position, so that the L-shaped clamping part of the clamping assembly 6 completely closes, and the cut rubber band is clamped in the circular area formed by the two semicircular clamping parts of the clamping assembly, so that the problem that the rubber band is easily bounced out or jumped out is prevented.

[0022] In the above embodiment, the front of the two semicircular clamping parts of the clamping assembly also has an extended bottom edge, which can effectively wrap the rubber band.
