the handle is provided with a cuboid connecting piece, a convex groove with a convex section is arranged on the cuboid connecting piece, one end of the convex groove starts from one end of the cuboid connecting piece in the length direction, the other end of the convex groove extends to the other end of the cuboid connecting piece, one end of the convex groove is sealed, and the other end of the convex groove is open; a protective sleeve is arranged on one side wall of one end, in an opening shape, of the cuboid connecting piece, a small spring is arranged in the protective sleeve, one end of the small spring is connected with the cuboid connecting piece, a pin body is fixedly arranged at the other end of the small spring, the other end of the pin body sequentially penetrates through the protective sleeve and the side wall of the cuboid connecting piece and continues to penetrate through the side wall of the cuboid connecting piece at the other side after penetrating through the convex groove, and the pin body are in sliding fit with each other after penetrating through the side wall of the cuboid connecting piece;
still include tension spring, tension spring's both ends symmetry is equipped with the T slider, and the symmetry sets up the T slider inlays respectively in the protruding inslot of difference handle and with protruding groove sliding fit.
As an improvement, the handle is provided with a loop rope which is sleeved on the wrist.
As an improvement, the cuboid connecting piece is matched with the handle through threaded connection.
As an improvement, the cuboid connecting piece and the protective sleeve are integrally formed.
Compared with the prior art, the utility model has the advantages that: the user can place the part that different quantity's tension spring and T sliding block constitute in the convex groove on the cuboid connecting piece, adjusts tensile dynamics. Has high commercial value and popularization value.

Detailed Description
The chest developer of the utility model with adjustable force is further described in detail with reference to the accompanying drawings.
With the help of the attached drawings, the chest expander convenient for force adjustment comprises two handles 1, a cuboid connecting piece 2 is arranged on each handle 1, a convex groove 3 with a convex section is arranged on each cuboid connecting piece 2, one end of each convex groove 3 starts from one end of each cuboid connecting piece 2 in the length direction, the other end of each convex groove 3 extends to the other end of each cuboid connecting piece 2, one end of each convex groove 3 is sealed, and the other end of each convex groove 3 is open; a protective sleeve 4 is arranged on one side wall of one end, which is in an open shape, of the cuboid connecting piece 2, a small spring 5 is arranged in the protective sleeve 4, one end of the small spring 5 is connected with the cuboid connecting piece 2, a pin body 6 is fixedly arranged at the other end of the small spring 5, the other end of the pin body 6 sequentially penetrates through the protective sleeve 4 and the side wall of the cuboid connecting piece 2, penetrates through the convex groove 3 and then sequentially penetrates through the side wall of the cuboid connecting piece 2 at the other side, and the pin body 6 are in sliding fit with each other after penetrating through the side wall of the cuboid connecting piece 2;
still include tension spring 9, tension spring 9's both ends symmetry is equipped with T slider 7, and the symmetry sets up T slider 7 inlays respectively in the convex slot 3 on different handles 1 and with convex slot 3 sliding fit.
The handle 1 is provided with a loop rope 8 which is sleeved on the wrist.
The cuboid connecting piece 2 is matched with the handle 1 through threaded connection.
