## Abstract

A portable motorized cutting tool has a motor housed in a tool body, a cutting member, a transmission linking the motor to the cutting member, and at least one guard for protecting the hand of the user, providing a passage for the hand around at least one of a control member of the tool, and a gripping handle of the tool. The tool has a cover capable of occupying a so-called “closed” position against the body of the tool, and a so-called “open” position separated from the body of the tool and giving access to a part of the tool protected by the cover in the closed position, the cover being linked to the body of the tool by the guard.

## Claims

### Claim 1

A portable motorized cutting tool comprising:
a tool body;
a motor housed in said tool body;
a cutting member;
a transmission connecting said motor to said cutting member;
a handle defined by a first portion of said tool body;
a tool control member arranged on a second portion of said tool body between the first portion of said tool body and said cutting member;
a protective guard adapted to allow a hand of a person using the portable motorized cutting tool to extend around said tool control member and said handle so as to grip the portable motorized cutting tool, the protective guard extends for a length of said handle and surrounds said tool control member, the protective guard being mounted to said tool body by a pivot, said pivot positioned at a rear portion of said tool body opposite to said cutting member relative to said handle;
a cover integral with said protective guard, said cover pivotable along with said protective guard about said pivot between a closed position against said tool body and an open position away from said tool body, the open position allowing access to a portion of said tool body protected by said cover in the closed position, said cover being connected to said tool body by the protective guard through said pivot in the open position and the closed position of said covert; and
a lock cooperative with said cover so as to keep said cover in the closed position, said lock being releasable by flexion of said protective guard toward said tool body.

### Claim 2 (depends on 1)

The portable motorized cutting tool of claim 1, wherein the portion of the tool body protected by said cover includes at least one of said transmission, a portion of said cutting member, an attachment for said cutting member, and an electric connector.

### Claim 3 (depends on 1)

The portable motorized cutting tool of claim 1, said lock comprising at least one latch and at least one retainer, the at least one retainer rigidly connected with the portion of the tool body protected by said cover, wherein the latch is retained in the retainer in one position and is released from the retainer in another position by flexing the protective guard.

### Claim 4 (depends on 3)

The portable motorized cutting tool of claim 3, wherein at least one of the latch and the retainer has a closure ramp and an opening threshold.

### Claim 5 (depends on 1)

The portable motorized cutting tool of claim 1, wherein said tool body has a housing defining the handle.

### Claim 6 (depends on 1)

The portable motorized cutting tool of claim 1, wherein said tool body has a first end bearing said cutting member and a second end that has an articulation for the protective guard, said first end being opposite said second end.

### Claim 7 (depends on 1)

The portable motorized cutting tool of claim 1, further comprising:
a safety device actuatable by said cover.

### Claim 8 (depends on 1)

The portable motorized cutting tool of claim 1, wherein the portable motorized cutting tool is a pruning shear, said cutting member has a fixed blade and a movable blade connected to said transmission.
