Further, two notches are symmetrically formed in the poking block, springs are fixedly connected to the notches respectively, the ends of the springs are fixed to the bottoms of the notches, rotating blocks are sleeved on the two springs, one ends of the rotating blocks, deviating from the bottoms of the notches, of the poking wheel shell are abutted to the inner wall of the poking wheel shell, a plurality of grooves with V-shaped cross sections are formed in the inner wall of the poking wheel shell, and the grooves are distributed along the inner wall array of the poking wheel shell.
Further, the poking block is cylindrical.
Further, a jack is formed in the center of the stirring block, one end, deviating from the knob, of the connecting rod is inserted into the jack, and the connecting rod is fixedly connected with the stirring block.
Further, two opposite side walls of the knob in the vertical direction are provided with holding grooves.
Further, the thumb wheel housing is cylindrical.
Further, the connecting rod is a rectangular rod.
The embodiment of the invention has the following advantages:
According to the embodiment of the invention, the knob, the spring, the rotating block and the thumb wheel shell are arranged, when the thumb wheel is used, the knob is held by fingers to rotate, the rotating of the knob can drive the connecting rod to rotate, and the connecting rod is fixedly connected with the poking block, so that the poking block rotates in the thumb wheel shell, the rotating block is always propped against the inner wall of the thumb wheel shell by the elasticity of the spring, the poking block rotates to further drive the rotating block to rotate, the structure is simple, the operation is more convenient, and the practicability is stronger.

Detailed Description
Other advantages and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms such as "upper", "lower", "left", "right", "middle" and the like are also used in the present specification for convenience of description, but are not intended to limit the scope of the present invention, and the changes or modifications of the relative relationship thereof are considered to be within the scope of the present invention without substantial modification of the technical content.
A rotary switch is shown in fig. 1, and comprises a dial wheel shell 1 with two open ends, a dial block 2 rotatably arranged in the dial wheel shell 1 and a knob 3 for driving the dial block 2 to rotate, wherein the dial wheel shell 1 is hollow and cylindrical, and the dial block 2 can rotate around the central axis of the dial wheel shell 1.
The inner wall of the thumb wheel shell 1 is provided with a plurality of grooves 11 with V-shaped sections, and the grooves 11 are distributed along the circumference of the inner wall of the thumb wheel shell 1 in an array.
The poking block 2 is cylindrical, and the shape of the poking block 2 is matched with the inner part of the poking wheel shell 1. The center position of the poking block 2 is provided with a jack, a connecting rod is fixedly connected in the jack, and one end of the connecting rod, deviating from the poking block 2, is fixedly connected with the knob 3. The central axis of the connecting rod is parallel to the central axis of the thumb wheel housing 1. The connecting rod in this embodiment is a rectangular rod.
Two notches 21 are symmetrically formed in the poking block 2, springs 4 are fixedly connected to the notches 21 respectively, one ends of the springs 4 are fixed to the bottoms of the notches 21, rotating blocks 5 are sleeved on the two springs 4, and one ends of the rotating blocks 5, deviating from the bottoms of the notches 21, are always abutted to the inner wall of the poking wheel shell 1 under the action of the elasticity of the springs 4.
