Retractor for helping patients to recover arm power

Abstract

The invention discloses a retractor for helping patients to recover arm power. The retractor for helping the patients to recover the arm power comprises a retractor body, connecting heads are integrally formed at two ends of the retractor body, handles are arranged at end parts of the connecting heads, connecting holes are formed in the middle positions of the two ends of the handles, sliding grooves are formed in the two sides of the end parts of the handles, compressing springs are fixedly installed in the bottom ends of the sliding grooves, and clamping heads are elastically connected to the end parts of the compressing springs. By arranging connecting rods and sliding blocks on the two sides of the connecting heads and arranging the sliding grooves on the two sides of the handles, thesituation that the handles of the retractor and the retractor are of an integrated structure, when the elasticity of the compressing springs of the retractor transforms and is damaged, the compressingsprings are inconvenient to replace and fixedly install, the clamping heads are compressed and fixed into clamping grooves through the internal sliding connection of the sliding blocks in the slidinggrooves and the action of elastic transform of the compressing springs so as to enable the sliding blocks to be fixed in the sliding grooves, and the connecting heads and the handles are fixed and used through the fixation of the sliding blocks and the connecting rods.

Description

technical field [0001] The invention belongs to the technical field of retractors, in particular to a retractor for helping patients recover their arm strength. Background technique [0002] The existing tractor is a device to help patients recover their arm strength. It provides multiple safety warnings and protections for patients.

Make the patient recover quickly and effectively; the existing retractor is an integrated structure of the handle and the retractor. When the compression spring of the retractor is deformed and damaged, it is not convenient to replace the compression spring and fix it. It is easy to It is easy to slip due to sweating of the hands, and it is not convenient to absorb sweat from the hands. Therefore, we propose a traction device to help patients recover their arm strength. Contents of...
