Abstract

A kind of hand-operated electrical compass saw which comprises a cabinet(10) with double-shell, a stroke rod(12) driven by electrical motor, a contact-preventing member(20). The stroke rod in the cabinet(10) can be guided to move along the axial direction and it has a clamping device(14) to accommodate a saw sheet. The member(20) is used to protect the fingers of operator from harm by serration of saw sheet. In order to make the member cheaper and satisfy the safety requirement and make the saw sheet(15) visible during working, the member(20) is designed as thin strip(21) and with one shell (101) of the cabinet(10) and extended in parallel to the saw sheet and in front of the serration row.

Make various contacts l &t; 1 I meaning 1 I to avoid injury 0 Matters 1 1 re 1 So far the conventional design of the anti-contact protection is P is good for the protection of the m fill in this note but once blocked the saw 1-1 in The line of sight of the m-entry position of the work object is not the page 1. Can + θ provide good and adequate protection to prevent injury. Their general structure cost is 1 1 high, and in the area where the anti-m guard is required, the field needs to be compatible with the field + fen to 1 1 the structure of the double saw 0. Therefore, the cost of the reciprocating saw with such contact guard 1 Ordering Λ has a negative impact on weight and convenience. 0 1 IL Advantages of the present invention 1 1 In contrast to the present invention, which has the characteristic point of the scope of patent application No. 1 1 The reciprocating saw of the present invention has the following advantages: The protective piece can not only satisfactorily exclude the various situations of contact with the saw LJ, but also can make the saw LJ unobstructed in the position of the saw in the crop 1 I. At the same time, this design is in the form of a thin strip 1 1 The guard has ribs for the huge measurement control of the sawing process because it can be used for 1 to be a saw tester. 0 This anti-contact guard can be cheaply made into a part integrally formed on the shell 1 1 body die And no need to install f, so no additional safety will be incurred. 1 I installation and storage costs 0 Since this contact protection is a 1 1 I part of the overall design of the reciprocating saw, it can show beauty and elegance. 0 1 1 The measures in the other sub-items of the patent application park can apply for patents ΪΒ around 1 1-3-1 1 This paper size applies to China National Standard (CNS) A4 size (210X 297 mm) A7 B7 j £ -Lizhangru Invention Description () The hand-operated electric reciprocating saw in the main item makes advantageous further development and changes the spring.
