Problems solved by technology

[0004] 1. The palm size of different people is very different. When using this type of grip, the grip strength cannot be changed at will, which reduces its comfort and reduces the applicable population;
[0005] 2. Uneven force of each finger when using;
[0006] 3. After the torsion spring is deformed after long-term use, the torsion spring needs to be replaced, but it is inconvenient to replace

Embodiment Construction

[0028] The following will be described in conjunction with the accompanying drawings and a specific embodiment.

[0029] see Figure 1 to Figure 2 . The basic structure of the power grip described in this embodiment includes two long connecting rods 1 parallel to each other and equal in length, on which a fixed rod 3, a movable rod 4, a finger rod 6 and a handle 2 are successively installed. , the fixed rod 3 and the movable rod 4 are connected through the elastic member 5; the movable rod 4 and the finger rod 6 are connected through the short connecting rod 7.

[0030] The fixed rod 3, the movable rod 4, the finger rod 6 and the handle 2 are parallel to each other. The fixed rod 3 and the handle 2 are respectively fixedly connected to the two ends of the long connecting rod 1, and the connection method can be threaded connection, and of course other connection methods in the prior art can also be used.

[0031] The movable rod 4 and the finger rod 6 are slidingly fitted wi...

Abstract

The invention discloses a wrist developer. Fixing rods, movable rods, finger rods and holding handles are sequentially arranged on two mutually-parallel and equal-length long connecting rods, the fixing rods and the holding handles are fixedly connected with the long connecting rods, the movable rods and the finger rods are in sliding fit with the long connecting rods, the fixing rods are connected with the movable rods through elastic components, and the movable rods are connected with the finger rods through short connecting rods. According to the wrist developer, the finger rods and the holding handles serve as two handles of two wrist developers, the finger rods are parallel to the holding handles, the finger rods can be pulled by all the fingers except for the thumbs, and the aim of training the finger joints in a balanced mode is achieved. Compared with the prior art, the wrist developer is high in comfort performance and wide in application scope.

Description

technical field [0001] The invention belongs to body-building equipment, and relates to a gripper. Background technique [0002] The grip is designed according to the shape of the human hand. When using it, it can be divided into one hand, two hands, upper grip, lower grip, double clamp and other different exercise methods. It is also called hand strength device, finger strength device, and force measuring device. The grip strength device is small and light, easy to carry, and it is not subject to any restrictions when used. It can exercise people's hand strength at any time and relieve fatigue. It is an essential small device for exercising and fitness. [0003] Existing grips have various structural forms, including sponge sleeve handle grips, rubber grips, adjustable grips and electronic grips. The electronic gripper is more advanced, but the price is higher. In the commonly used sponge sleeve handle grip, the two ends of the two handles are connected by torsion springs...
