Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model;

referring to fig. 1 to 4, a fast-mounted bicycle crank comprises a main shaft 1, wherein cranks 2 are arranged on the left side and the right side of the main shaft 1, teeth 4 are arranged on the left side and the right side of the two main shafts 1, tooth grooves 3 matched with the teeth 4 are formed on the opposite sides of the two cranks 2, mounting grooves 5 are formed in the two cranks 2, positioning handles 6 are arranged on the left side and the right side of the cranks 2, mounting holes 7 are formed in the inner walls of the two positioning handles 6 and the two mounting grooves 5, round pins 8 are arranged on the top and the bottom of the main shaft 1, two clamping grooves 9 are formed in the front of the main shaft 1, and clamping blocks 10 matched with the clamping grooves 9 are fixedly connected to the inner sides of the two positioning handles 6.

When the crank 2 is installed, the positioning handle 6 is firstly placed into the corresponding installation groove 5, then the installation hole 7 on the positioning handle 6 is aligned with the installation hole 7 on the installation groove 5, at the moment, the round pin 8 is inserted into the installation groove 5 from the installation hole 7 on the crank 2, at the moment, the round pin 8 can be inserted into the positioning handle 6, further the installation of the positioning handle 6 is realized, then a user inserts the main shaft 1 into the frame, the installation of the main shaft 1 can be realized, at the moment, the user inserts two ends of the main shaft 1 into the two tooth grooves 3 respectively, teeth 4 at two ends of the main shaft 1 are meshed with the corresponding tooth grooves 3, further the positioning of the crank 2 is completed, then the user presses down the positioning handle 6, the positioning handle 6 is attached to the inner wall of the installation groove 5, at the moment, the clamping block 10 can be inserted into the clamping groove 9 on the main shaft 1, and the clamping block 10 is matched with the clamping groove 9, and further the positioning and the locking of the crank 2 are realized.

Please refer to fig. 1-4, wherein: one side of the positioning handle 6 is fixedly connected with a turnover block 11, and the surface of the turnover block 11 is provided with anti-skid patterns.
