Examples

The embodiment of the utility model relates to a tool for picking a graphite chuck of a single crystal furnace, which comprises an upper body 10 and a lower body 12, wherein the upper body 10 is a hollow cylinder for accommodating a heavy hammer part; the lower body 12 has an inverted cone structure for accommodating the graphite chuck part; simultaneously, the whole lower body 12 passes through the upper body 10 from bottom to top, the upper part of the lower body is sleeved in the upper body 10, and the heavy hammer and the graphite chuck are accommodated in the same space by adopting the upper body 10 and the lower body 12 with different specifications through the picking tool.

Further, the utility model also comprises a plurality of handles 14, wherein through holes 13 are symmetrically arranged on the side walls of the upper body 10 and the lower body 12 respectively, and the handles 14 can be detachably inserted into the inner part of the upper body 10 and the inner part of the lower body 12 respectively through the through holes 13. The number of handles 14 and the number of through holes 13 are in one-to-one correspondence, and the handles 14 are detachably connected with the upper body 10 and the lower body 12 through the through holes 13, respectively. Because the surface of the graphite chuck is smooth and difficult to screw when the graphite chuck is just dismounted, the through holes 13 and the handles 14 are arranged, on one hand, in order to clamp the heavy hammer and the graphite chuck, the friction is increased, and the screwing is convenient; on the other hand, when the lower body 12 is loaded, the space for accommodating the lower body 12 can be provided, and meanwhile, heavy hammers and graphite chucks with various sizes can be fixedly removed.

Further, a first limiting protrusion 101 is provided at the bottom end of the upper body 10 along the horizontal line in the extending direction, and the diameter of the first limiting protrusion 101 is smaller than that of the upper body 10. The purpose of the first limiting protrusion 101 is to limit the top end of the lower body 12 when the lower body 12 is placed in the upper body 10, so that the top end of the lower body 12 is located on the upper portion of the first limiting protrusion 101, and the lower body 12 is prevented from falling.

Further, a second limiting protrusion 121 is provided at the top end of the lower body 12 along the horizontal line in the extending direction, and the diameter of the second limiting protrusion 121 is smaller than that of the upper body 10. The second limiting protrusion 121 is provided to penetrate the lower body 12 into the upper body 10, on the one hand, and is provided to be mutually screwed in cooperation with the first limiting protrusion 101, on the other hand.

Further, the diameter of the second limiting protrusion 121 is larger than that of the first limiting protrusion 101. The diameter of the second limiting protrusion 121 located at the top end of the lower body 12 is larger than that of the first limiting protrusion 101 located at the bottom end of the upper body 10, so that the second limiting protrusion 121 is placed above the first limiting protrusion 101 for detachable connection.

Further, both ends of the handle 14 are arc-shaped. Because the outer peripheral surfaces of the heavy hammer and the graphite chuck have a certain radian, the two ends of the handle 14 are provided with the arc shapes which are more matched with each other and are contacted with the heavy hammer and the graphite chuck, and the clamping force is increased.

Further, the bottom of the lower body 12 is closed. The lower body 12 with the closed bottom is arranged, so that a graphite chuck can be better borne, and further, the phenomenon that the graphite chuck falls off is prevented, and the potential safety hazard phenomenon is avoided.

Further, the inner circumferential surface of the upper body 10, the inner circumferential surface of the lower body 12 and the arcuate surfaces of both ends of the handle 14 are made of a tetrafluoro material, and the outer circumferential surface of the upper body 10, the outer circumferential surface of the lower body 12 and the grip portion of the handle 14 are made of a stainless steel material. The polytetrafluoroethylene material can be further anti-skid and high-temperature resistant, and the thickness of the polytetrafluoroethylene material is reasonably set on the premise of ensuring certain anti-skid and high-temperature resistant properties. The stainless steel material can further improve the hardness and rigidity of the whole picking tool, and ensure that deformation cannot occur in the screwing process.

Specifically, the working principle of the utility model is as follows: firstly, the bottom end of the lower body 12 is penetrated into the upper body 10, and as the top end of the lower body 12 is provided with the second limiting protrusion 121 and the bottom end of the upper body 10 is provided with the first limiting protrusion 101, the second limiting protrusion 121 enables the part of the lower body 12 with the diameter size larger than that of the first limiting protrusion 101 to be left above the first limiting protrusion 101 for connection; meanwhile, the diameter of the second limiting boss 121 is smaller than that of the upper body 10, so that under the screwing action of the handle 14, the upper body 10 is fixed with the heavy hammer to be screwed leftwards, the lower body 12 is fixed with the graphite chuck to be screwed rightwards, the heavy hammer is separated from the graphite chuck, the operation mode is simple, and meanwhile, the knocking of the graphite chuck is avoided. The closed bottom of the lower body 12 avoids the problem of damage caused by falling and smashing of the graphite chuck. And the part contacted with the heavy hammer and the graphite chuck is made of a tetrafluoro material, so that the anti-skid and high-temperature-resistant performances are improved.

The foregoing description of the preferred embodiment of the utility model is not intended to limit the utility model in any way, but rather to cover all modifications, equivalents, improvements and alternatives falling within the spirit and principles of the utility model.
