The fixing assembly 50 includes a fixing base 51, a limit bearing 52 and a positioning clamp spring 53, the fixing base 51 is detachably connected to the cover plate 20, the fixing base 51 includes a disk-shaped fixing base 511 and an annular fixing sidewall 512, a sidewall connecting hole array composed of sidewall connecting holes 5121 is disposed on a top of the fixing sidewall 512, the sidewall connecting holes 5121 and the cover plate connecting holes 22 are respectively connected through a connecting screw 60, a guiding notch array composed of guiding notches 513 is disposed on a circumferential direction of the fixing sidewall 512, guiding baffles 514 are disposed on two sides of a rear portion of the guiding notches 513, and spring bayonets 5141 are disposed on top portions of the guiding baffles 514.
The side wall of the fixed side wall 512 is provided with a hanging ring 516, which is convenient for the user to hang.
The fixed base 511 is provided with a fixed cylinder 515 at the center thereof, the limit bearing 52 is disposed at the bottom of the fixed cylinder 515, the positioning clamp spring 53 is disposed in the fixed cylinder 515 and above the limit bearing 52, the rotating shaft 312 penetrates the positioning clamp spring 53 and the limit bearing 52, the positioning clamp spring 53 includes an annular clamp spring main body 531, a positioning protrusion array composed of arc-shaped positioning protrusions 532 is disposed on the inner wall of the clamp spring main body 531, and the function of the positioning clamp spring 53 will be described later.
A tool head assembly 40 is respectively disposed in the guiding slots 513, the tool head assembly 40 is respectively slidably disposed in the guiding slots 513, the tool head assembly 40 includes a tool head 41 and a return spring 42, the tool head 41 includes a square column shaped batch seat 411, the head of the batch seat 411 is provided with a batch head 412, the tail of the batch seat 411 is provided with a tapered batch tail 413, the top of the batch seat 411 is provided with a spring clamp 4111, the top of the batch tail 413 is provided with a recessed positioning groove 4131, the return spring 42 includes an annular spring clamp ring 421 and a pair of spring arms 422, the ends of the spring arms 422 are respectively provided with a spring 423 clamp, the spring clamp ring 421 is matched with the spring clamp 4111, and the spring clamp 423 is matched with the spring clamp 5141.
Wherein the tool head 41 is between a storage position and an operating position, when the tool head 41 is in the storage position, the tool head 41 is retracted in the guiding slot 513, and when the tool head 41 is in the operating position, the extrusion protrusion 314 presses the tool head 41 and extends the tool head 41 out of the guiding slot 513.
The method of using the carousel tool 10 is described in detail below.
As shown in fig. 12 and 13, the tool heads 41 are in the storage position, the tool heads 41 are retracted in the guide slots 513, and the drip-shaped extrusion protrusions 314 are caught between the tails 413 of two adjacent tool heads 41. At this time, the positioning ridge 313 on the side wall of the rotating shaft 312 abuts between the two positioning protrusions 532 of the positioning clamp spring 53, preventing the rotating head 31 from rotating and shaking freely.
When a user needs a certain tool head, as shown in fig. 14 and 15, the user can press the thumb against the rotating finger plate 33 and rotate the entire rotating head 31 clockwise, the water drop-shaped extrusion bump 314 presses the batch tail 413 of the tool head 41, and at the same time, the tool head 41 continuously extends outwards in the guide notch 513 until the tip of the extrusion bump 314 abuts against the positioning groove 4131 of the batch tail 413, and the tool head 41 is in the working position, so that the user can use the tool head 41 to complete the screwing or unscrewing operation. At this time, the positioning ridge 313 abuts between the two positioning protrusions 532 of the positioning clamp spring 53 again, so that the tool bit is prevented from shaking during use. After use is over, the entire swivel head 31 is again swiveled by means of the swivel finger plate 33, so that the drop-shaped extrusion cam 314 returns to the position shown in fig. 12, while the tool head 41 is retracted into the storage position within the guide slot 513 under the action of the return spring 42.
It should be noted that the carousel tool 10 employs six tool heads, and it is apparent that more tool heads may be used. The tool head 41 is a quincunx screwdriver, and may be other tool heads, such as an inner hexagon, a straight line shape, etc.
In addition, the return spring 42 may be replaced with other resilient members or extrusions, such as coil springs, spring pins, leaf springs, etc., so long as the tool bit has a tendency to retract inwardly in the guide slots 513.
In addition, a retractable door can be arranged at the head of the guide slot 513, when the retractable door is closed, external dust can be effectively prevented from entering the tool, the tool head can be effectively prevented from accidentally protruding from the guide slot 513, and the safety is further improved.
When the tool heads are in the storage positions, all the tool heads are not exposed, so that the tool heads are conveniently hung on the key ring and do not scratch clothes. The user can control all the tool heads by rotating the finger disc 33, which is simple and convenient and is suitable for daily carrying.
In addition, the cover plate 20 and the fixed base 51 are magnetic, so that a plurality of turntable type tools 10 can be overlapped to form a tool group, and more tool heads can be used.
In addition, the extrusion lug 314 and the tool head 41 are both magnetic, and reliable stability is maintained by the tool head 41 by virtue of its rapid retraction.
Referring to fig. 16, a second embodiment of the tool bit of the present invention is shown, in which a batch head 412 is detachably connected to a batch seat 411. The batch seat 411 is provided with a batch seat screw hole 4110, the batch head 412 comprises a batch head body 4121 and a batch head screw 4122, and the batch head screw 4122 is matched with the batch seat screw hole 4110. Since the batch head 412 and the batch seat 411 can be quickly separated and connected, a user can quickly replace various batch heads.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
