Improve as one, on the axle of described hand crank, connect driving gear, on the front axle head of described bent axle, driven gear is installed, described driving gear and driven gear are connected by meshing transmission.
As improving further, it is the first circular chute that described base both sides are provided with vertical cross section, described the first chute wall is provided with vertical cut (V. cut), in described the first chute, be slidably fitted with slide block, described slide block extends to form hinged installation portion through described vertical cut (V. cut), the top of described gripper shoe is hingedly mounted on hinged installation portion, and the two ends screw thread of described the first chute is provided with bolt, and described bolt and described slide block offset.
Improve as another kind, described gripper shoe comprises two gripper shoe bodies setting up and down, lower supporting plate body is provided with the second chute, upper backup pad body is slidably mounted in the second chute of lower supporting plate body, the through hole that is provided with some mutual correspondences on the second chute cell wall of described lower supporting plate body with upper backup pad body, arranges pin in described through hole.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
Owing to being provided with bent axle and hand crank in base, by shake hand crank, pressing lever is moved up and down, press patient chest, and the bottom of pressing lever is provided with sucker, when pressing lever moves upward, attract chest to move upward, expand thoracic cavity volume, laborsaving and be not subject to the restriction of operating environment when use, be provided with gripper shoe and base plate, when use, form triangle robust structure, support effect is good, uses quick and convenient, while use, can will support by packing up with base plate, be convenient to place and carry.
On axle due to hand crank, connect driving gear, on the front axle head of bent axle, driven gear is installed, driving gear and driven gear are connected by meshing transmission, set the gear ratio of driving gear and driven gear, the frequency of pressing can be set, can select as required suitable ratio gear, easy to use.
Because gripper shoe is hingedly mounted on the hinged installation portion of slide block, slide block slides up and down along base, is convenient to the height of adjusting base when use, to regulate press head according to pressing depth, easy to adjust.
Because gripper shoe comprises the two gripper shoe bodies that are slidably installed together, and fix the convenient height that regulates gripper shoe by pin.
