However, this kind of conventional structural pattern has found that the following problems still exist in the actual experience:

The problem is how to develop an internal separation component that is very complicated. The cost of structural materials is increased, which in turn causes the consumer to become a consumer. The more cost-effective innovative structure that exists in the fast component device of the conventional circular saw saws, and the use of the M337436 is as expected. It is also the relevant industry's efforts to develop breakthrough targets and development evaluation. In view of this, the creators have been engaged in the design and design of related products for many years, and the design and finalization of the above objectives are practical. The creation of sex. Eight [new content] that is, 'the main purpose of this creation' is to provide a kind of circular saw

The component device; the problem to be solved is that the internal separation material member existing in the conventional electric (gas) dynamic circular hole saw drilling quick joint structure is 18 complicated and complicated in structure, and the material which needs a large increase in structure is required. Cost, the problem of causing the cost burden of the industry to improve the breakthrough. And its technical characteristics of solving the problem, mainly through the hole saw, one end is provided with a through hole, the side end of the group hole is set to φ - empty | 牙 a dental hole, and the front end of the joint body is provided with a set portion 'to provide a hollow aw < bud group hole disassembled in the hole silver, and the other end of the joint body forms a transmission groove for the set driving device, Inside the transmission slot, there is a through hole, and the joint body is corresponding to the circular saw saw; <female, the singer has a hole and a hole, and a locating pin is used for the tooth set in the hole of the joint body, B々°丨, five locating pins • Aligning the perforations in the circular saw, wherein the rear end of the locating pin is provided with a guiding end, and the side edge of the guiding end is formed with a blocking portion, which is used for - Hy π π Μ _ 销 pin wears behind the elastomer and stops at a blocking portion, wherein the positioning member is formed with at least two guiding inclined faces corresponding to the end faces of the guiding ends of the positioning pins, and the two guiding guides and the second positioning portions are respectively formed with the high positioning portion and the low positioning portion by positive and negative directions. Rotate the enemies, and use 1 to make the positioning pins of the W fans guide the high positioning part or the low positioning part of each guiding slope, and push or export the perforations of the circular saw before and after the forced displacement. 7 M337436 (4) The new unique design enables the creation and joint body to be guided by the positioning lock, and the structure is only wrongly moved by the positioning saw and the driving device to smoothly remove the round hole effect, and by the positioning member The combination of the two to achieve the power ^ - the position of the pinning teeth extended to the circular saw saw each of the driving force device can smoothly drive the circular ore drill heavy load or large:: 'to make the industry; according to the prior art, this creation Up to two drilling: Practical and progressive use of convenience and ease of use.
